Ship Engines and Power Plants II

At the end of this course, the students should be able to: 1. identify and analyse ship main engines (types and configurations such as CODAG, CODOG, COGAS and electric drives); 2. describe the general machinery layout and do proper heat balance analysis of power plants; 3. design power plant systems, propeller shaft, boilers and ship service systems; and 4. recommend power plants for special vessels (fishing vessels, tugs.).

Types of ship power plants and factors affecting the choice of power plant type. Ship main engines: Types and configurations, combined propulsion systems such as CODAG, CODOG, COGAS etc., and electric drives. General machinery layout. Heat balance analysis, overall efficiency determination and comparison across different power plant types. Design of power plant systems: Fuel oil systems, sea water cooling systems, lubricating oil systems, compressed air systems, steam systems, exhaust gas system, fresh water systems, automatic control and alarm systems. Propulsion shaft line arrangement, gear boxes, bearings and seals. Marine steam boilers: classifications, components, materials selection, principles of operation, instrumentation and automatic control. Boiler survey, corrosion mitigation and maintenance. Waste heat recovery systems. General purposes systems: bilge, ballast, water; firefighting. Rules and Regulations guiding design of ship power plants such as Lloyds register, American bureau of shipping, etc., and environmental protection requirements. Powerplants for special ship: fishing vessels, tugs/pushers tankers and passenger ships.
